York S1-124247 TXV

Professional-grade York S1-124247 TXV is a high-capacity thermal expansion valve engineered for precise refrigerant metering in large-scale residential and commercial systems. This genuine OEM component serves as the factory-authorized updated version for S1-526-36283-000, ensuring seamless integration and restored volumetric efficiency. Featuring robust 1-1/8" x 1-3/8" ODF sweat connections and a 1/4" external equalizer, this valve is designed to handle the rigorous pressure drops associated with high-tonnage evaporators. The 5-foot capillary tube and sensing bulb provide ample reach for optimal placement on the suction line, allowing for rapid response to load fluctuations and stable superheat control. By maintaining the ideal liquid-to-vapor transition point, the York S1-124247 prevents liquid slugging at the compressor while maximizing heat transfer across the coil. This replacement HVAC expansion valve is a critical York HVAC part for contractors maintaining 14 SEER+ systems requiring consistent performance under varying ambient conditions.

• Precise Superheat Regulation: Optimized to maintain target superheat, preventing compressor damage and ensuring high system efficiency.
• Direct OEM Substitute: Specifically replaces legacy part number S1-526-36283-000 without the need for extensive line set modifications.
• Heavy-Duty Construction: Built with high-grade brass and copper to withstand high-pressure R-410A or R-22 environments.
• Extended Capillary Reach: The 5' lead allows for flexible sensing bulb positioning to accurately monitor suction line temperatures.

What are the connection sizes for the S1-124247?
This TXV features 1-1/8 inch inlet and 1-3/8 inch outlet ODF sweat connections, with a 1/4 inch equalizer line.

Can I use this to replace the S1-526-36283-000?
Yes, the S1-124247 is the official updated replacement for the S1-526-36283-000, designed to meet the same technical specifications and performance curves.

Is an external equalizer necessary for this installation?
Yes, for the high-tonnage systems this valve supports, the 1/4" external equalizer is required to accurately compensate for the pressure drop across the evaporator coil.
